Grizzly BearvsSaltwater Crocodile

This is almost entirely environment-dependent. On land, the grizzly is faster, more mobile, and can use its paw swipes to devastating effect against the croc's relatively immobile body. In water, the croc's death roll and underwater maneuverability make it lethal.

On neutral ground (shallow water or riverbank), the fight is a genuine toss-up. The croc's ambush advantage and armored body contest the bear's mobility and striking power. In real life, bears and crocodilians occasionally encounter each other and the results are mixed — usually both prefer to avoid the confrontation.

The bear's weight advantage (900 lbs vs ~700 lbs for a large croc, though saltwater crocs can reach 2,200) means this varies dramatically based on individual size.
